Homicide Cold Case Register
In accordance with Arizona Revised Statutes (A.R.S.) 13-4271, The Maricopa County Sheriff’s Office Homicide Unit maintains a cold case register. The cold case register consists of the name of any victim, victim’s family member or other lawful representative of a victim of a cold case. The register provides current contact information to be used by law enforcement personnel for contact purposes in the event that new developments in the case occur.
